I agree. Endless Space just works.

for what its worth, I'm also on Arch and lack the file Kisak had mentioned. Instead I have nvidia_icd.json. Endless space works great for me.

Hi @kisak-valve

Thanks for the suggestion.

No, the only file I have in that directory is nvidia_icd.json

It is working on Debian 10

I played a few hours, several turns.

I only have the file nvidia_icd.json inside /usr/share/vulkan/icd.d/

My Specs:
Distro Debian 10
Driver: NVIDIA Corporation GeForce GTX 1070 Ti/PCIe/SSE2
Driver Version: 4.6.0 NVIDIA 390.77
Desktop: Mate

Installed everything from Debian repository or default, I have not added any extra config or parameter.

Here is the link to my Steam system info:

Confirmed.

Distro: Linux Mint 19 Tara
Processor: AMD Ryzen 7 1700
GPU: GTX 1070, Nvidia proprietary driver 396.54
RAM: 32GB
Kernel (custom) - 4.17.14 (optimized for Ryzen)
Resolution: 1920x1080
Proton 3.7-3

I crashed......even not start...

I'm getting a crashed due to access violation errors...
EndlessSpace.exe caused an Access Violation (0xc0000005) in module EndlessSpace.exe at 0023:00484169.

I have moved the intel_icd.i686.json and intel_icd.x86_64.json files out of the way. The only files remaining are radeon_icd.i686.json and radeon_icd.x86_64.json. However, I am running the Nvidia proprietary driver module, there are no nvidia .json files in /usr/share/vulkan/icd.d/

Any ideas?

For Proton 6.3-3 and current Experimental (6.3-20210503) placeholder TV test patterns are shown instead of videos, both for intro and "start of the new game" videos. Seems like a part of https://github.com/ValveSoftware/Proton/issues/1464

I just tested it: I can see the Amplitude and Iceberg opening logo videos (never seen them before), but I get the test pattern placeholder for a brief moment when starting a new game, just before the tutorial window shows up.

Proton: 1631125536 experimental-6.3-20210908
SteamGameId: 208140
Command: ['/home/norman/.local/share/Steam/steamapps/common/Endless Space/EndlessSpace.exe', '-single-instance']
Options: {'forcelgadd'}
depot: 0.20210818.24
pressure-vessel: 0.20210809.1
scripts: v0.20210818.0-0-gc6be089
soldier: 0.20210817.0 soldier 0.20210817.0

This is the most I can get as a log output when trying to start the game. It never even brings up a window, just flashes the play button to 'cancel', 'stop', and then back to play.

I have tried versions of proton going back to 3 and all the way up to experimental. I have tried GE builds. I am out of ideas. What am I missing and where should I go from here?

Replying to https://github.com/ValveSoftware/Proton/issues/740#issuecomment-917300768

I deleted the Proton prefix for this game, relaunched, and it worked like a charm. I do not know why I did not think of that sooner, and wanted to update.

@jn64 There are transcoded videos available - as you mentioned, they will not play because you have shader pre-caching disabled. This game does not use Proton's h264 implementation and relies on the transcoded videos.
